Cognitive tests included in the Collaborative European NeuroTrauma Effectiveness Research traumatic brain injury battery, the domains that they primarily assess, and the specific measures that were used in analyses
| Test | Domains | Measure |
| CANTAB Paired Associate Learning | Visual learning and memory | Total errors adjusted (ie, errors for all trials, allowing for trials not completed) |
| Rey Auditory-Verbal Learning Task | Verbal learning and memory | Total correct words recalled for the 15-item principal list over 5 trials |
| Trail Making Test A | Attention and processing speed | Time to draw lines between 25 numbers in sequence (s) |
| Trail Making Test B | Attention and processing speed, task switching | Time to draw lines in alternating sequence between 13 numbers and 12 letters (s) |
| CANTAB Choice Reaction Time | Processing speed | Median decision time for correct responses (ms) |
| Motor speed | Median movement time for correct responses (ms) | |
| CANTAB Rapid Visual Processing | Sustained attention | A’ (A prime): accuracy of target detection calculated from hits and correct rejections |
| Sustained attention | Latency of correct responses (ms) | |
| CANTAB Attention Switching Task | Attention, task switching | Total correct responses |
| Attention, task switching | Median latency of correct responses (ms) | |
| CANTAB Spatial Working Memory | Strategy and working memory | Between errors: number times a search is incorrectly repeated for the same location. |
| CANTAB Stockings of Cambridge | Planning, problem solving | Trials solved in the minimum possible moves |
